Using the BOOT Menu
TFTP (Trivial File Transfer Protocol) is a simple file transfer protocol that is used
without complex interaction between clients and servers.
The client initiates a TFTP transmission. To download files, the client sends a read
request packet to the TFTP server, receives the packet from the server, and sends
the acknowledgement to the server. To upload files, the client sends a write
request packet to the TFTP server, sends the data packet to the server, and receives
the acknowledgement from the server.
The Switch 7700 provides the functions of the TFTP client.
A TFTP Server program is shipped on the CDROM with the Switch 7700.
Before you upgrade:

■
and that it is enabled and pointing to the correct directory.
To upgrade using TFTP:

File-Optional>
3 Set the boot parameters to specify the file to boot the system from, using the
